The error comes from Premiere itself, so generally speaking it should be addressed by Adobe.

Please prepare a small test case -- a project with one short clip and one effect (Neat Video) that allows to reproduce the problem and send it to support [at] neatvideo.com for analysis. We will reproduce the problem and check what is causing it. If it is something in Neat Video, then we will fix the plug-in. If it is a problem in Premiere, we will forward it to Adobe.
